GPR 1300 engine warning light HELP

Few week a go i had the gpr out for about 4ohrs when the engine warning light come on.No codes on the screen and the ski still ran fine.Today took it out againe and after 5min of rideing the engine warning light come on againe.What is the reason this light would come on?
The ski runs fine no problems at all.I thort a sensor plug may have come off but i cant find any thing obvious.I have been told maybe the cat may be stufft and to replace it with a d-plate but im thinking if this was the reason wouldnt the cat warning light come on?
has any one had this problem or have any other ideas to what it may be.

Did you take the connectors apart and inspect the pins for corrosion ?
May want to spray them off with some contact cleaner and then reseat them and see if the problem persists.

You may just have a intermittent connection due to corrosion.

I did check all the conections that i could get to but need to take off the exhaust to get to the engine temp sensor.Trying to get my hands on a d-plate and when i do ill take it all apart and check it out.

i think i found the problem.the rectifier was coroded as well as the plugs.Turns out i had a charging problem as it was only geting 11.3v
will see if i can get some parts tomoro and give it another go.

i was speeking to danny the bloke who use to work at jet1 and he picked up on it so i whent to pull the plug off the rectifier and it was jamed on.Puled the battery box out to get a little more room and found that it was coroded on.When i finaly got it off one of the pins broke in 1/2 and the other 5 where black and smelt like arcing.it was prity bad.Will hunt around tomoro for a new reg and plug.danny said it was a recal on the 2003 with the loom as the plugs didnt have copper terminals.he was going to change the hole loom and rectifyer for around 450 but i think i might just get a new one and just fix that plug as the rest of the loom is still like new.If i can get a plug off a later modle as they have the copper pins ill get that and seal it up a little better than std and it should be good.

just glad i found the prob but we will see how we go when its back together.

p.s the ski runs alot smoother with the D-plate but i dont think its got as much off the marc as what it did.But holds top end speed a lot better tha be for
